So this thread is apparently quite dead, but in case anyone still has one of these and is still playing around with it, I just picked one up used, and am enjoying it very much, feel free to keep in touch.
I've been reading a lot on the more active ga6400 thread as that was the successor model and some of what they are doing is still applicable.

The motortrend app is very good, but so far that is all I have found useful in the marketplace.
I deleted everything I had side loaded, and just went back to the basic apps after the first week of use.
